Activation of the Spx redox sensor counters cysteine-driven Fe(II) depletion under disulfide stress

Abigail G. Hall, Abdulelah A. Alqarzaee, Aliyah J. Collins, Sasmita Panda, Svetlana Romanova, Sujata S. Chaudhari, Andrew J. Monteith, Dorte Frees, Vinai Chittezham Thomas

This study shows that the Spx redox switch in S. aureus is critical for managing cysteine levels during disulfide stress, preventing Fe(II) depletion and growth inhibition.

A D-alanine aminotransferase S180F substitution confers resistance to β-chloro-D-alanine in Staphylococcus aureus via antibiotic inactivation

Rakesh Roy, Yahani P. Jayasinghe, Sasmita Panda, Merve Suzan Zeden, Vinai Chittezham Thomas, Donald R. Ronning, James P. O’Gara

This study identifies a S180F substitution in D-alanine aminotransferase (Dat) in Staphylococcus aureus that confers resistance to β-chloro-D-alanine by altering PLP co-factor binding and promoting antibiotic inactivation.
